THRESHING IWACHINE.

SPECIFICATION forming part of Letters Patent No. 691,116, dated January 14, 1902.

Application filed April 15, 1901. Serial No. 55,916. (No model.)

To CLZZ whom it may concern:

Be it known that I, GEORGE F. CONNER, a citizen of the United States, residing at Port Huron, in the county of St. Clair and State of Michigan, have invented certain new and useful Improvements in Threshing-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertai'ns to make and use the same. 7

This invention relates to improvements in threshingmachines, and has for its object to provide improved means for bracing and strengthening the frame of the machine, including side supports which serve the combined purposes of braces to resist side strains and tool-box holders, the supports and toolboxes acting also to form a ladder, whereby convenient access to the top of the frame is afforded.

To this end the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a top plan View of a threshing-machine embodying my invention. Fig. 2 is a fragmentary rear end elevation thereof, on an enlarged scale, showing the rear axle and side braces; and Fig. 3 is a fragmentary side elevation showing the parts disclosed in Fig. 2.

Referring now more particularly to the drawings, 1 represents the body or frame of the machine, 2 the front supporting-axle, and 3 the rear supporting-axle. The roof of the frame is reinforced and strengthened at the center and rear by a V-shaped brace a and at the front by angular braces 5, which are crossed to form an X-shaped stay, said braces being composed of metallic straps or angle-iron and suitably secured to the body of the machine. These braces strengthen the roof in such a manner as to resist side strains to the frame and tend to keep the body or frame in a true position.

The rear supporting-axle 3 extends through the hub of the rear supporting-wheel 6 and has connected to its projecting end two diverging braces 7, forming in connection with an upper cross-bar 8, which connects said braces at their upper ends, a V shaped strengthening-frame, which is reinforced at its lower end by a short cross-bar 9, extending parallel with the cross-bar 8 and connecting the braces a short distance above the axle 3. The diverging braces are preferably constructed of angle-iron to give the requisite strength. Above the diverging braces are inclined supporting-bars 10, which are connected at their upper ends to the sidewall or frame of the body 1 and at their lower ends to the upper ends of the said diverging braces 7 and extend on an outward and downward inclinationfromtheframe toapointoverandimmediately beyond the wheel 6. These braces and supporting-bars also act to resist side strains to the frame and tend to keep the frame inatrue position. The drawings show the side braces and supporting-bars arranged upon one side of the frame only; but it will of course be understood that the same structure may be du- Dlicated upon the other side of the machine. To the side wall of the frame are secured one or more intermediate supports 11 in the form of tool-boxes, which are also secured to and extend between the inclined supporting-bars 10. These boxes, in addition to serving as holders for tools, act as intermediate braces, connecting the supporting-bars 10 to each other and to the frame 1, and afford a firm and stable arrangement of stays for the parts. The said intermediate braces or tool-boxes also serve the function of steps cooperating with the cross-bars 8 and 9, which also serve as steps, and in connection with the braces 7 and inclined supporting-bars 10 these boxes and cross-bars form a ladder which afiords convenient access to the roof or top of the frame 1.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of the invention will be readily understood without a further extended description. Changes in the form, proportion, and

minor details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a threshing-machine, the combination with the supporting-axle'and body, of a V- shaped brace-frame connected with the axle, inclined supporting-bars connected between said V-shaped frame and side wall of the body, and one or more intermediate braces secured to the body and to said supportingbars and forming the steps of a ladder of which the braces and supporting-bars constitute the side rails, substantially as described.

2. In a threshing-machine, the combination with the supporting-axle and body, of diverging braces connected to the axle, one or more cross-bars connecting said braces, a pair of inclined supporting-bars connected to the upcomic per ends of the diverging braces and extending therefrom to, and connected with, the side wall of the body, and boxes secured to the side wall of the body and supporting-bars and forming in connection with the said crossbars the steps of aladder-frame of which the braces and supporting-bars constitute the side rails, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

GEORGE F. (BONNER.
